For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0036] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0037] For reference Figure 1 This application constructs a pyramid cube, which is tetrahedral and may include an axis group 1 (see reference). Figure 2 The core group 1 serves as the skeleton of the pyramid cube; multiple corner pieces 2, edge pieces, and center pieces can be installed on the outside of the core group 1 to form the surface structure of the pyramid cube.

[0038] The corner piece component 2 forms the corners of the pyramid cube and the surfaces adjacent to the corners; the edge piece component forms the edges of the pyramid cube and the surfaces adjacent to the edges; and the center piece component forms the remaining surfaces of the pyramid cube. It should be noted that there are multiple corner piece components 2, edge piece components, and center piece components. The number of edge piece components and center piece components may vary depending on the order of the pyramid cube; please refer to relevant technical specifications for details, which will not be elaborated upon here.

[0039] Can be combined Figure 2 and Figure 3 For reference, the pivot assembly 1 includes a central support 11; since the pyramid cube is tetrahedral, the central support 11 has four pivot portions 111. The pivot assembly 1 also includes a connecting frame 12 connected to each pivot portion 111 for providing a mounting base for at least some edge piece assemblies and center piece assemblies.

[0040] like Figure 2 As shown, any connecting frame 12 may include a first connecting frame 121 and a second connecting frame 122 connected to the shaft portion 111. The first connecting frame 121 and the second connecting frame 122 are generally triangular in shape, and the first connecting frame 121 and the second connecting frame 122 are spaced apart in the axial direction of the shaft portion 111 to form part of the active area. Understandably, the active area refers to the spatial area that supports the rotational movement of the center block assembly and the edge block assembly. The active area covers the outer space of the connecting frame 12, the inner space of the connecting frame 12, and the inner space of the connecting frame 12.

[0041] Differentiate based on installation location, please refer to... Figure 2The multiple edge pieces can be divided into a first edge piece assembly 3 installed in the connecting frame 12 and a second edge piece assembly 4 installed on the outside of the connecting frame 12. Since in related technologies, the second edge piece assembly 4 may fall off during rotation of the pyramid cube, this application redesigns the second edge piece assembly 4 and the structure around it to ensure reliable assembly, thereby solving the problem of the second edge piece assembly 4 potentially falling off during rotation.

[0042] The following is Figure 1 The 5x5 pyramid Rubik's Cube structure shown is used as an example for further explanation. In the 5x5 pyramid Rubik's Cube structure, based on position, as follows... Figure 1 As shown, the multiple edge pieces can be divided into center edge pieces and edge pieces. The center edge piece can be located at the midpoint of an edge of the pyramid cube, and the edge piece can be located between the center edge piece and the corresponding corner piece 2. Since the center edge piece is configured and installed within the connecting frame 12, it is equivalent to the first edge piece 3 described above. The edge piece is configured and installed on the outside of the connecting frame 12, not within it, and is therefore equivalent to the second edge piece 4 described above. Hereinafter, the center edge piece will be referred to as the first edge piece 3, and the edge piece will be referred to as the second edge piece 4.

[0043] like Figure 2 As shown, each first edge block assembly 3 is connected between two adjacent connecting frames 12. Each first edge block assembly 3 has three spaced-apart sheet-like structures 33 to form a first slot 31 for the corresponding second connecting frame 122 to be inserted, and a second slot 32 for the surrounding center block assembly to be inserted. The first slot 31 and the gap between the first connecting frame 121 and the second connecting frame are located on the same circumferential direction. Furthermore, the first edge block assembly 3 may have two outer surfaces facing outward to form the surface structure of two adjacent faces of the pyramid cube.

[0044] Secondly, each central block component is provided with at least one third slot 54 (see reference). Figure 2 This allows for the insertion of the surrounding first edge block assembly 3, other center block assemblies, or connecting frame 12. Secondly, some center block assemblies also have at least one insert portion 55 (see reference). Figure 4 ), used to be inserted into the third slot 54 of other center block components, or at the connecting frame 12, or at the first edge block component 3.

[0045] Continue to refer to Figure 1Based on their location and structure, the multiple central block components can be divided into several first central block components 51, several second central block components 52, and several third central block components 53.

[0046] In this pyramid, on one side, the outer surface of the second center block assembly 52 is adjacent to the outer surface of the corresponding corner block assembly 2; the outer surface of the first center block assembly 51 is adjacent to the outer surface of the edge block assembly; and the outer surface of the third center block assembly 53 is located within a circle formed by the outer surfaces of several first center block assemblies 51.

[0047] In some embodiments, reference may be made to Figure 1 and Figure 2 Each second center block assembly 52 can be a structure with an internal hollow channel, fitted onto the shaft portion 111 of the central support 11, and positioned relative to the outer side of the connecting frame 12. The second center block assembly 52 can have three outer surfaces facing outwards to form the surface structure of three adjacent faces of the pyramid cube.

[0048] Secondly, continue to refer to Figure 4 Each first center block component 51 may have two outer surfaces facing outwards to form the surface structure of two adjacent faces of the pyramid cube. The first center block component 51 may be fitted between two adjacent third center block components 53, which refer to two third center block components 53 located on two adjacent faces of the pyramid cube respectively.

[0049] For example, such as Figure 4 As shown, the first center block assembly 51 has a third slot 54 on one side adjacent to the nearest second center block assembly 52 and on one side adjacent to the nearest first edge block assembly 3, for inserting the first connecting frame 121 and the sheet structure 33 of the first edge block assembly 3; at the same time, the first center block assembly 51 has an insert portion 55 on both sides adjacent to the two nearest third center block assemblies 53, for inserting into the third slot 54 of the two nearest third center block assemblies 53.

[0050] Also, please refer to Figure 1 and Figure 2 Each third center block component 53 may have an outer surface facing outwards to form the surface structure of one face of the pyramid cube. The third center block component 53 can be engaged between adjacent center block components. For example, a third center block component 53 located at the very center can be engaged between other adjacent third center block components 53; while a third center block component 53 located outside the center can be engaged between an adjacent first center block component 51 and other third center block components 53.

[0051] It can be further noted that the first center block assembly 51 and the second center block assembly 52 can also be configured to have only one outer surface, which can be adjusted according to requirements. The structural design of the first center block assembly 51 and the second center block assembly 52 in this embodiment can help improve the assembly efficiency of the Rubik's Cube.

[0052] In some embodiments, reference may be made to Figure 5 Each second edge piece assembly 4 may include a body portion 41, a limiting portion 42, and a connecting portion 43 connecting the body portion 41 and the limiting portion 42. The body portion 41 is used to form part of the surface structure of the pyramid cube; the connecting portion 43 is used to extend into the interior of the pyramid cube; the limiting portion 42 is used to lock into the internal structure of the pyramid cube to prevent the second edge piece assembly 4 from accidentally coming out. Correspondingly, see [reference]. Figure 3 The interior of the pyramid cube has a receiving area 6 for accommodating the limiting part 42. The wall of the receiving area 6 can abut against the limiting part 42, thereby preventing the edge pieces from coming out.

[0053] like Figure 5 As shown, the main body 41 can be a triangular pyramid-shaped structure with two outer surfaces facing outwards to form the surface structure of two adjacent faces of a pyramid cube.

[0054] The connecting portion 43 can be a flat, elongated structure. The main body 41 and the limiting portion 42 are disposed on opposite ends of the connecting portion 43. One end of the connecting portion 43 can be connected to the edge of one side surface of the main body 41, and the other end is connected to the limiting portion 42 at an angle. The connecting portion 43 has two opposing surfaces. The surface closest to the corner block assembly 2 is flat and flush with one side surface of the main body 41, while the other surface is a convex arc surface.

[0055] The surface of the limiting part 42 facing away from the connecting part 43 is curved, and the curvature of the curved surface is related to the rotational movement of the second prism assembly 4. Furthermore, the limiting part 42 may include two limiting units, namely a first limiting unit 421 and a second limiting unit 422. The shapes of the first limiting unit 421 and the second limiting unit 422 are adapted to the spatial size of corresponding positions in the accommodating area 6. In other words, the shape and size of the first limiting unit 421 and the second limiting unit 422 may be different, or they may be the same; this is not limited here.

[0056] In this embodiment, reference can be made to Figure 2The first limiting unit 421 is disposed relatively close to the second center block assembly 52, and the second limiting unit 422 is disposed relatively close to the first center block assembly 51. The first limiting unit 421 can be a plate-like structure and is connected to the connecting portion 43 at an angle. The thickness of the second limiting unit 422 can be greater than that of the first limiting unit 421, and similarly, the second limiting unit 422 is connected to the connecting portion 43 at an angle. The surface of the second limiting unit 422 facing the body portion 41 is closer to the body portion 41 than the surface of the first limiting unit 421 adjacent to the body portion 41, and the surfaces of the first limiting unit 421 and the second limiting unit 422 that are away from the body portion 41 form a flat arc surface. The surface of the second limiting unit 422 facing the body portion 41 is an inclined surface relative to the connecting portion 43. There is a gap between the second limiting unit 422 and the body portion 41, and part of the structure of the first center block assembly 51 can be disposed between the second limiting unit 422 and the body portion 41. The two opposing surfaces of the second edge block assembly 4 and the second center block assembly 52 are parallel.

[0057] Can be reviewed Figure 4 A second clearance space 512 is provided between the second center block assembly 52 and the corresponding first center block assembly 51. The receiving area 6 is provided on the side of the second clearance space 512 near the axis assembly 1, and the connecting part 43 can be provided in the second clearance space 512.

[0058] Let's look again. Figure 3 The accommodating area 6 may include a first gap 61 formed between the second center block assembly 52 and the first connecting frame 121. The first limiting unit 421 may be disposed in the first gap 61. Furthermore, the wall of the second center block assembly 52 may block the first limiting unit 421 from moving outward, thereby preventing the second edge block assembly 4 from coming outward.

[0059] The receiving area 6 may also include a first clearance position 62 formed on the side of the first center block assembly 51 adjacent to the second center block assembly 52. ​​The second limiting unit 422 may be disposed at the first clearance position 62. Furthermore, the wall of the first center block assembly 51 may block the second limiting unit 422 from moving outward, thereby preventing the second edge block assembly 4 from dislodging outward.

[0060] Continue to refer to Figure 4The first center block assembly 51 has a structural surface 511 facing the second center block assembly 52 on one side adjacent to it. A second clearance position 512 can be recessed into the structural surface 511. Simultaneously, the second clearance position 512 can be positioned in the middle of the structural surface 511. When the connecting part 43 is inserted into the second clearance position 512, the surface of the connecting part 43 facing the second center block assembly 52 is flush with the structural surface 511, allowing the pyramid cube to rotate normally.

[0061] It should be noted that the Pyramid Cube may also include other components inside, but since these components are not the focus of this application, their description is omitted. For details, please refer to relevant technologies; they will not be elaborated upon here. Similarly, the operating principle of the Pyramid Cube can be found in relevant technologies; it will not be elaborated upon here.

[0062] In summary, the assembly process between the second center block assembly 52, the second edge block assembly 4, and the first center block assembly 51 can refer to the following steps:

[0063] S1: First, the second center block assembly 52 is fitted onto the shaft portion 111 of the center support 11;

[0064] S2: Then, the second edge block assembly 4 is installed on one side of the second center block assembly 52; at this time, the first limiting unit 421 of the second edge block assembly 4 is inserted into the first gap 61 formed between the second center block assembly 52 and the first connecting frame 121.

[0065] S3: Finally, the first center block assembly 51 is positioned between the two adjacent third center block assemblies 53 and the first edge block assembly 3 after assembly; at this time, the second edge block assembly 4 is sandwiched between the first center block assembly 51 and the second center block assembly 52, the second limiting unit 422 of the second edge block assembly 4 is located at the first clearance position 62 of the first center block assembly 51, and the connecting part 43 of the second edge block assembly 4 is located at the second clearance position 512 between the first center block assembly 51 and the second center block assembly 52.

[0066] Understandably, the cooperation between the first limiting unit 421 and the wall at the first gap 61, the cooperation between the second limiting unit 422 and the wall at the first clearance position 62, and the cooperation between the connecting part 43 and the wall at the second clearance position 512 can prevent the entire second edge piece assembly 4 from accidentally coming off in multiple directions, especially during the Rubik's Cube rotation process.

[0067] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
